Migration step 2 fails

[briri]

Ran into the following issue when running the second migration step:

Brians-MacBook-Pro:roadmap briley$ rake db:migrate
rake aborted!
Could not load configuration. No such file - /Users/briley/Documents/workspace/roadmap/config/branding.yml
/Users/briley/Documents/workspace/roadmap/config/application.rb:100:in `<class:Application>'

(See full trace by running task with --trace)

Got past it by creating an empty branding.yml. It then failed because mysql2 is not a part of the Gemfile. I think we need to add it back since most existing installations will be using mysql2

Brians-MacBook-Pro:roadmap briley$ touch config/branding.yml
Brians-MacBook-Pro:roadmap briley$ rake db:migrate

Uncommented the mysql2 gem in the Gemfile and things began working properly.

[briri]

I'm not sure of the best approach to splicing these changes back into the commit history since we we need them to exist at a particular point within the tree.

I think others are likely to encounter the same issue. I ran this today on my laptop. I'll run again tomorrow on my work machine to see if I get the same errors

[briri]

This was unfortunately an issue again when running through the steps on my work machine so we should decide how to address it.

I noted that the branding.yml file existed in the old_schema tag and then disappeared when switching to the transitional_schema tag.

We should update the git history to un-comment the mysql2 gem in the Gemfile and just add an empty stub config/branding.yml.

see #108 for possible course of action

Added a pkey to the users_perms table: CDLUC3@9682648

Closing this one since we've been discussing the entire migration process steps1-3 in #108
